FILLING-REPLENISHING LOOM.

SPECIFICATION forming part of Letters Patent No. 680,601, dated August 13, 1901.

Application filed June 6, 1901. Serial No. 63,433. (No model.)

To all whom, it may concern:

Be it known that we, JOHN J. LANE and LOUIS A. AUMANN, citizens of the United States, residing at Ohicopee, in the county of Ham pden and State of Massachusetts,have invented an Improvement in Automatic Fillin g-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

In United States Patent No. 641,792, dated January 23,1900, a 100m is shown provided with automatic filling replenishing mechanism and with a thread-parter to part the thread in use between the shuttle and the cloth upon a change of filling, the threadparter being movable with a shuttle-feeler into position to part the thread, means being provided for thereafter actuating the parter to part the thread. In such apparatus the change of filling is not permitted to take place if the shuttle-feeler engages the shuttle, as will be the case if the shuttle is improperly boxed, but the thread-parter may be operated and the filling-thread may be severed, so that the shuttle will be returned through the shed without laying filling, resulting in a mispick. A comparatively slight deviation in the position of the shuttle in the box is sufficient to render the replenishing mechanism inoperative through the shuttle-feeler and properly in order to prevent a smash when the filling is changed, but it will be manifest that owing to the position of the filling-thread near the front of the lay sufficient retraction of the thread-parter will not ordinarily be effected to also prevent parting of the thread.

Our present invention has for its object the production of means, in mechanism substantially such as is disclosed in the patent referred to, to positively prevent the actuation of the thread-parter, even should the usual shuttle-feeler fail to prevent its bodily movement into position to engage the fillingthread.

In accordance with our invention, therefore,we have provided independent means for controlling the operation of the thread-parter,

such means being governed by or through the shuttle when improperly boxed.

Figure 1 is aright-hand side elevation of a 100m provided with filling-replenishing mechanism, one embodiment of our presentinvention being shown in connection therewith. Fig. 2 is an enlarged plan view of a part of the loom, showing the thread-parter in position ready to part the filling-thread in use between the cloth and the shuttle; and Fig. 3 is an enlarged transverse sectional view. on the line 00 00, Fig. 2, looking toward the left.

As in said Patent No. 641,792, the fillingcarriers are mounted in. a rotatable feeder F, from which they are removed one by one by a transferrer f, fulcrumed atfand having a depending end f on which is mounted a spring-controlled notched dog m having a lateral lug an, engaged by an upturned arm y of a yoke Y, fulcrumed on the loom side at 5, the dog being moved into the path of a hunter 0 on the lay A when the usual controlling rock-shaft (Z is rotated in the direction of the arrow 50, Fig. 1, a detent-finger d fast on the rock-shaft, engaging a projection 6 on the yoke and maintaining the latter normally in the position shown by means of a strong spring S The yoke-arm y herein is likewise shown as upturned and bent rearwardly to act as a shuttle-feeler, its extremity being notched, as at p, and the fixed and movable parting-blades p p are mounted on the shuttle-feeler, the blade 19 having a de- I operation of the controlling means for the filling replenishing mechanism the yoke Y is swung upon its fulcrum 5, and if the shuttle S is properly boxed the thre'ad-parter will be moved into the position shown'in Figs. 2 and 3, the filling-thread t entering the notch pof the feeler and -between the parting-blades 19 p Thereafter as the lay completes its forward beat the actuator will engage the heel 135, and the parting-blades will act upon and sever the thread 25 in well-known man ner, the thread-clamp being also operated as in said patent. It will be noted, however, by reference to Fig. 2 that even should the shuttle be out of the box far enough to engage the feeler y and prevent the operation of the fillingreplenishing mechanism still the thread 15 would be between the blades 19 p and the latter would be closed by the actuator C on the beat up of the lay. In order to positively prevent this action of the threadparter, we have mounted on the feeler-arm 3 at its outer side, a sliding dog 01 having-a longitudinal slot 61 entered by two supporting and guide studs 60 60, (see Fig. 8,) a spring 5 attached atone end to the dog and at its other end to a pin 62 on the feeler, normally holding the dog in the position shown. A shoulder (Z on the inner face of the dog is in engagement with the front end of a plate e fulcrumed at e on the feeler y and held by the action of the spring 5 against a stop 6 The inner end of the plate, which may be termed an auxiliary shuttle-feeler, is cut away to present a beak 6 which projects rearwardly alongside of the notch 19 and partly covers it, as shown in Fig. 3. An auxiliary actuator or bunter E on the lay extends forward considerably in advance of the main actuator C and is adapted to engage the dog d if the latter is moved in the direction of arrow 75. Now if the shuttle is not fully in the shuttle-box, but has permitted the thread-parter to move into position to receive the thread 1. between its blades, then the tip of the shuttle will engage the beak e as the lay beats up and will lift the beak, de-

pressing the front end of the plate e which in turn moves the dog 01 in the direction of the arrow 75 into the path of the auxiliary actuator E The lay completes its forward movement, and in so doing the actuator E engages the dog (Z and moves it, and consequently the feeler y and the parting-blades thereon, toward the front of the loom, so that the main actuator 0 cannot engage the heel 10 to close the blades, and the latter will not be closed upon the thread to part it. It will be manifest, therefore, that the thread t or the thread in use cannot be parted if the filling-replenishing mechanism is not permitted to operate, so that there will be no mispick, and as soon as the lay moves back the spring .9 returns the dog (Z and auxiliary feeler e to normal relative position.

By reference to Fig. 1 it will be seen that the lower beveled face of the hunter O has been elongated by the addition thereto of an extended safety-deflector 80, which acts upon the upper corner of the dog m when the latter is prevented from moving into full operative position by the shuttle-feeler y. Such engagement of the dog with the deflector acts to further depress the dog-when the lay completes its forward movement, so that it is impossible for the dog to accidentally spring up into the path of the hunter C Our invention may be modified or rearranged without departing from the spirit and scope of our invention, one practical embodiment thereof being herein shown and described.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a loom provided with filling-replenish ing mechanism, controlling means therefor, a shuttle adapted to carry a supply of filling, a th read-parter, bodily movable by or through the operation of the controlling means into position to part the filling-thread in use, a device to normally actuate the thread-parter when so positioned, and independent means to positively prevent such actuation of the thread-patter if the shuttle is improperly boxed.

2. In a loom provided with filling-replenishing mechanism, controlling means therefor, a shuttle adapted to carry a supply of filling, a shuttle-feeler, a thread-parter movable therewith into position to part the fillingthread in use upon a change of filling, an actuating device for the thread-parter, and means operative independently of the said shuttle-feeler to prevent actuation of the thread-parter when the shuttle is improperly boxed.

3. In a loom provided with filling-replenishing mechanism, controlling means therefor, a shuttle adapted to carry a supply of filling, a thread-parter, bodily movable by or through the operation of the controlling means into position to part the filling-thread in use, the lay, main and auxiliary actuators thereon, the former being adapted to normally actuate the thread-parter when placed in operative position, and independent, normally inoperative means rendered operative by or through the shuttle when improperly boxed, to be engaged by the auxiliary actuator and moved to prevent cooperation of the thread-parter and the main actuator.

4. In aloom provided with filling-replenish ing mechanism, controlling means therefor, a shuttle adapted to carry a supply of filling, a shuttle-feeler, a thread-parter mounted thereon and bodily movable by or through the operation of the controlling means into position to part the filling-thread in use, an actuator to normally effect the operation of the thread-parter when so positioned, and in-= dependent means actuated by engagement with the tip of the shuttle to positively retract the shuttle-feeler and move the threadparter away from the filling-thread if the shuttle is not fully and properly boxed.

5. In a loom provided with filling-replenishing mechanism, controlling means therefor, a shuttle adapted to carry a supply of filling, a shuttle feeler, fixed or movable threadparting blades bodily movable therewith by or through the operation of the controlling means to receive between them the fillingthread in use, the lay, a main actuator thereon to close the blades when so positioned, to part the thread, an auxiliary feeler mounted adjacent said blades and adapted to be moved by the shuttle if not properly boxed, a dog adapted to be operatively positioned by such movement of the auxiliary feeler, and an auxiliary actuator on the lay and extended forward beyond the main actuator, to engage the dog when in abnormal position, to thereby bodily retract the partin g-blades and prevent cooperation of the main actuator therewith.

6. In aloom provided with filling-replenishing mechanism, controlling means therefor, a shuttle adapted to carryasupply of filling, a shuttle-feeler, a thread-parter mounted thereon, and bodily movable by or through the operation of the controlling means into position to part the filling-thread in use, an actuator to normally effect the operation of the thread-parter when so positioned, and independent means to elfect bodily retraction of the thread-parter beyond the thread-path if the shuttle-feeler fails to detect an improper boxing of the shuttle.

7. In aloom provided with filling-replenishing mechanism, controlling means therefor, a shuttle adapted to carry a supply of filling, a shuttle-feeler to prevent the actuation of said mechanism if the shuttle is improperly boxed for a change of filling, a thread-parter bodily movable with the shuttle-feeler into position to part the thread of the filling-carrier to be ejected from the shuttle, a device to normally actuate the thread-parter when so operatively positioned, and independent means adapted to be operated by the shuttle if the latter is not fully boxed to bodily retract the thread-parter beyond the path of the thread, to thereby prevent parting of the latter when the filling in the shuttle is not changed. v

8. In a loom provided with filling-replenishing mechanism, controlling means therefor, including a pivotally-mounted dog, a shuttle adapted to carry a supply of filling, the lay, a hunter thereon to engage and move the dog when operatively positioned, to effect actuation of the filling-replenishing mechanism, an elongated safety-deflector on the bunter, and a shuttle-feeler, operatively connected with the dog, to prevent movement of the latter into operative position when the shuttle is improperly boxed, the safety-deflector at such time engaging the end of the dog and positively deflecting it out of the path of the hunter.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
